Abstract: 1,105,975. Ultraviolet absorption analysis; photo-meters. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N. V. June 11, 1965, No. 24791/65. Headings G1A and G1P. [Also in Division G2] The concentration of oil in water is determined by first extracting the oil from the water with a solvent such as chloroform and then determining the concentration of oil in the solvent by ultraviolet absorption analysis either continuously or batchwise. In the absorptiometer shown in Fig. 2 having two measuring units A and B, ultraviolet light from a mercury arc lamp 12 after passing through an iris diaphram 18 enters a viewing cell 9 through which the solvent containing the oil is passing continuously. The absorption is measured at a wavelength of 2537 A, the mercury omission line, by means of two filters, one a solution of nickel chloride sealed in a quartz container 15" and the other a glass filter 15'. The light at this wavelength which is for maximum absorption by the oils passes to a cadmium sulphide cell 13 provided with a phosphor 16' to convert the ultraviolet light to visible light. An indication and record is provided and an alarm given of the oil level reaches a certain limit. The same ultraviolet light-source may provide beams for passage through further cells through which the solvent may flow successively or one of these further cells may provide a reference.

IPC: B41F13/30
Filed: 1957-08-07
Abstract: 830,678. Rotary printing machines. DE LA RUE CO. Ltd., [formerly DE LA RUE & CO. Ltd., T.]. April 3, 1958 [Aug. 7, 1957], No. 24947/57. Class 100(2) An impression cylinder 11 is mounted in bearing blocks 13 slidable between surfaces 16,17, while a plate cylinder 12 is mounted in bearing blocks 14 secured to a frame 15. A vertically slidable block 20 is connected to each block 13 by studs 18, 19. Coil springs urge the blocks 13 upwardly. Toggles 26, 27 engaging grooves in blocks 22, 23 are connected to a rod 28 reciprocated by a lever 29 on a cam driven shaft 30, so timed that the impression cylinder is raised and lowered alternately each half revolution of the cylinder 12. A wedge member 31 is mounted between the frame 15 and the upper block 23. The member 31 is secured to a plate 32 actuated to insert or withdraw the member 31 by a screw 33. A worm wheel 34 on the screw 33 is rotatable through a worm 35 on a shaft 37 by a handwheel 40. Thus, rotation of the handwheel varies the printing pressure by raising or lowering the impression cylinder. A cable 41 secured to the plate 32 at one end and wrapped around an indicator disc 49 at the other end indicates the position of the wedge 31 and permits the application of a desired printing pressure. A steel rod 44 attached to the block 20 operates a dial gauge 46 to indicate extension of the studs 18, 19 and thus the pressure between the impression and plate cylinders 11, 12. The plate cylinder 12 carries a fixed pinion having a pitch circle smaller than the cylinder diameter, while the impression cylinder 11 has a freely rotatable pinion, having a pitch circle of the same diameter as the cylinder 11. The plate cylinder pinion is driven and drives the impression cylinder during one revolution of the latter when not printing. During printing, the impression cylinder is fricttionally driven by the plate cylinder upon operation of a slip gear mechanism in the manner described in Specification 830,677.

Filed: 1956-08-16
Abstract: 816,444. Copy-turning. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. Aug. 16, 1956, No. 25138/56. Class 83 (3). In a lathe, the tool-slide is fed by a differentialpiston 2, Fig. 1, in a cylinder 1 supplied at both ends simultaneously by an hydraulic pump 3. The pressure at the larger end 6 of the cylinder is controlled by varying the outlet 10 by axial movement of a plunger or drum 18, which is rotated at 19 from the head-stock spindle. A roller 13 engages the drum and is carried by a pivot 14 rotatably adjustable at 15 in a slide 11 movable parallel to the drum axis bv a rod 11a, together with the piston 2 and tool-slide. The roller is adjustable angularly to allow it to roll without friction along a helical line on the drum so long as the spindle-speed remains constant, but if this varies, the rotational speed of drum 18 will change and produce an axial-thrust on the roller. This thrust moves the drum axially, to enlarge or decrease the outlet 10 and thus vary the traversing-speed of the piston 2, toolslide and slide 11 until the roller 13 again follows a frictionless helical path on the drum. The pressure in the hydraulic system is controlled by a spring-loaded valve 7 which allows excess fluid to flow to the sump 9 through a pipe 8. The angularity of roller 13 may be adjusted with the aid of a scale and pointer (Fig. 3, not shown). In a modification, a valve controlling the outlet 10 is connected to slide 11 and piston 2, and the drum 18 has no axial movement. In another modification, a disc 18b, Fig. 6, is rotated from the head-stock spindle and is engaged by the roller 13 connected by a rod 25 to the valve for outlet 10 to give a variable linear-movement to rod 25. The roller is then set to traverse a spiral path on the disc. In a further modification, the drum 18 has a varying diameter from end to end, and the drum 18 and roller 13 are moved along curved paths so that the traverse-speed of the tool-slide is varied in a predetermined manner relatively to the spindlespeed. In another modification, the tool-slide 22 and slide 11, Fig. 9, are traversed by an electric motor 29 and feed-screw 30, and the roller 18d is used to vary a resistance in the motor-circuit, or switch the motor on and off, to maintain the traverse-rate proportional to the spindle-speed.
